Title: The Tale of Two Branch Points: Singularities in 2D flows
Abstract:
The problem of 2D surface gravity waves is considered from the standpoint of
singularities persistent in the analytic continuation. A new approach to study wave
breaking, rogue waves is based on dynamics of complex singularities propagating
in the analytic continuation outside of the fluid domain. New integrals of motion are
found to be associated with these singularities, and efficient numerical methods can
be designed by exploiting the dynamics of such singularities and allow to simulate
even the tallest oceanic waves. Do the new motion integrals indicate integrability of
2D water waves? The question remains open...
About the Speaker: Prof. Sergey Dyachenko, is a UNM Alumni (PhD 2014, advisors Pavel M. Lushnikov and Alexander O. Korotkevich). His Dissertation was titled "Strongly Nonlinear Phenomena and Singularities in Optical, Hydrodynamic and Biological Systems". After that Dr. Dyachenko spent a year (2014-2015) as a Visiting Assistant Professor at the Mathematics Department, University of Arizona. Later Prof. Sergey become a J. L. Doob Research Professor at the Mathematics Department, University of Illinois Urbana-Champaign, where he was from 2015 till 2019, with a short leave for a year (2016-2017) as a Postdoctoral Fellow at the Institute for Computational and Experimental Research in Mathematics (ICERM) at Brown University, Providence, RI. Later (2019-2020) Prof. Dyachenko become Acting Assistant Professor at the Applied Mathematics Department, University of Washington, Seattle, WA. Since 2020 he is Assistant Professor at the Mathematics Department, State University of New York at Buffalo, NY. Recently one of his publications on ocean waves in the Proceedings of the National Academy of Sciences have got wide media coverage.
Seminar will be through Zoom:
